CHARCQAL-FUHNACE.

iM-. The Schedule referred to in these Lettve's Patent and making part of the samev To all whom it ina-y concern;v

Be it known that I, WILLIAM T. DOWNS, of St. Louis, in the county .of St. Louis, and State of Missouri, have made certain new and useful Improvements in Charenal-Furnaces; and l do hereby de clare the following to be a full and correct description thereof', reference being had to the accompanying drawings, and to the letters of reference marked thereon.

This invention relates to the furnaces usually employed in small households for cooking and other heating-purposes; and

The nature of this invention is, first, in the arrangement ol'a boiler or reservoir for oater, or similar fluids, permanently upon the sides of the furnace;

` and secondly, iny the manner of arranging a number of removable Apartitions within the furnace, so that iu case a smaller heating-surface is required than the wholcfnrnace would "ive with no er econom" a wart ofthe furnace may then be used,'said part forming in itself a completo furnace.

To enable those herein skilled to make and use my/ said improvements, l will now more fully describe the same, referring to the accompanying- Figure 1 as a plan, with the cover removed; to Figure 2 as a sectional elevation, transversely; to

Figure 3 as a partiront View'.

I form said furnace of cast-iron O r other similar material, ot' an elongated body, A, having, usually, rounded ends, and` generally approximating to the form of the .so-called clnu'cOal-fu'rnaces now in common use.

Said furnace has the bottom B, and is supported upon legs'in the ordinary manner. f

Above said bottomLand resting upon the inclined ends of lthe fin-nace, is the grate C., arranged, generally, as usual.

The main draught-opening D is arranged centrally in the front ot' the furnace-body, supplying air to the fuel placed u pon the grate C.

On the body A, I rest. the cover E, arranged with the usual pot-holes, and having proper lids.

vIn said cover isthe chimney or smoke-escape F.

lo the body A of my said furnace, I connect the boiler G, forming therewith a reservoir, in which water is placed. Said boiler will usually be connected with the rear wall of the body A, but mav be connected with the ends of said body.

mize the heat of thcfmnace in heatingr the'fluid,

which finds useful application in many of the necessities of housekeepin". Said boiler and its fluid thus acts to prevent the departure of heat from thc furnace to great advantage in hot temperatures, and therefore causes great relief from excessive radiatiouofheat, to the operator or cook, in hot weather, this being the period whensaid furnaces are usually employed in cooking, ironing, &c.

Within the body Afl arrange the removable partitions H, having prongs h., by which they arc held in positiomon the body A, and lnwingsinular prongs projectingbetween the grate-bars, to preventdislocation. At the upperV edge of said partitions, I url-ke a smoke-passage, H', through which thc gases of combustion pass, to reach the space between said partitions, and from this find an exit at the chimney F.

In the front of the furnace, I arrange the side .lx'auglit-openings I, leading to each of the spaces eni closed by cach partition.

lhe arrangement of said parts is, therefore, such,

that in case a small fire is required, thesaine maybe made in the sub-furnaces K or K', and thus an econonly of fuel lnay be achieved.

When the'` entire furnace is nccdedtbr heating, the partitions-H maybe'lifted out, and even then 'the sidedraught passages I will be found useful to regulate the combustion in the ends of the furnace.

A damper-plate may he used to close the main draught-passage D, when only one sub-furnace, K, is required.

Having thus fully described my said invent-ion,

1. The arrangement of the furnace A and boiler G, substantially as and for the purposes set forth.

2. The body A, grate C, 'partitions H, smoke-passages H', cover E, and chimney F, substantially ,as set forth. l

Inwitncss of said invention, I have hereunto set my hand, in the presence ofv WILLIAM T. DOWNS.
